DIPHENYL DITELLURIDE Chemical Properties,Usage,Production

Chemical Properties

Orange to brown crystals and powder

Uses

Diphenyl ditelluride may be used in the assay of organolithium and Grignard reagents.

General Description

Diphenyl ditelluride (PhTe)₂ is a versatile reagent used in the organic synthesis. Neurotoxicity by (PhTe)₂ depends on the modulation of signaling pathways initiated at the plasma membrane. Comparative toxicological effects of diphenyl diselenide and (PhTe)₂ in mice after in vivo administration has been reported. Teratogenic effects of (PhTe)₂ on chicken embryo development has been investigated. The oxidative addition of (PhTe)₂ to [Pd(PPh₃)₄] in dichloromethane is reported to yield [Pd₆Cl₂Te₄(TePh)₂(PPh₃)₆]·1/2CH₂Cl₂.
